Abstract

An apparatus for playing a disc on which, in addition to a coded information signal, a digital information signal divided into blocks is recorded as a subcode together with a block identification signal for identifying the blocks, comprises a reading device for reading the coded information signal and the subcode from the disc, a decoder for decoding the subcode to produce an information signal, a repeater for repeating the subcode read out by the reading device to the decoder in response to a repeat command, and a controller for controlling the reading device and the repeater. The controller issues, in response to a command, a jump command for moving an information reading point of the reading device across M (M is a natural number) tracks in a direction retracing a reading direction every time a predetermined time period corresponding to the relative position of the information reading point in a radial direction of the disc elapses; detects, during a period between issuing of the jump command and issuing of the next jump command, an N-block period, in which N (N is a natural number) blocks of the subcode are read, by a block identification signal obtained from an output signal of the reading device; and supplies the repeating command to the repeater only during the N-block period.
